Most times, waiting for something to be not to be considered, we have to go towards it and grab it, instead of sitting down and waiting (there is a popular saying in my local, that says "if the mountains do not come to Muhammad, then Muhammad should go to the mountains) and I have been following that step instead of waiting for the dip.
I don't consider waiting for the dip a good way of investing, but if we eventually invest during the dip, then we should take advantage of it (even if it's a Satoshi we can afford at that time).
I agree with you. Years of experience in looking at the history of Bitcoin we can see clearly that waiting for a decline will not bring good results. It's better for you to save little by little. I see a lot of people who keep waiting for the price to go down because in their minds all they have is 1BTC and 0.1BTC even though wouldn't it be possible to buy 0.00001 BTC if we only had enough money to buy that much?
